Office building at Fabianinkatu

Designed by Alvar Aalto in the 1960s, this office and commercial building was originally an extension to the Nordic Union Bank. It stands between Aleksanterinkatu and Esplanadi Park, with views over one of Helsinki’s most popular green spaces. Today the building is also home to Paradox Museum Helsinki, an interactive museum with more than 40 rooms of optical illusions and visual surprises.
